![]() My client, an owner of several ports, wanted to build and own a new WID, to replace one that was on hire. (The owner also owns one of the world’s largest dredging companies.) They built two – both are in operation even today. A totally out-of-box concept from a Dutch Naval Architect who could somehow convince his friend, the owner, to give it a shot. But the WID is a relatively new concept, just around 50 years or so. ![]() Without a WID, the only option is a TSHD which is quite ludicrous and extremely expensive as you will be dredging a large amount of water with an insignificant amount of loose soil.Ĭonventional dredgers (TSHDs, CSDs, etc) have been around for a very long time. The WID removes the soft soil – efficiently and economically. But the master will adhere to the depth displayed in the echo-sounder and refuse to enter the port. The soil is soft and will not damage to a ship or its propeller. A normal echo-sounder of a ship displays the navigable depth up to top of this soil layer. In ports which are tidal, there is often deposit of very loose soil on the hard bed. But it does “ bring up” – not outside but within the water. an apparatus for bringing upobjects or mud from a river or seabed by scooping or dragging. ![]() clear the bed of (a harbour, river, or other area of water) by scoopingout mud, weeds, and rubbish with a dredge.A totally out-of-box concept from a Dutch Naval Architect, unexplored in India till this vessel.
